There are two main types of hair transplant:
- Follicular unit strip surgery (FUSS). The surgeon will remove a strip of skin from the donor area and close the incision with stitches. They will then use a microscope to separate the donor skin into tiny follicular units that contain one or several hair follicles and insert these units into the desired area.
- Follicular unit extraction (FUE). The surgeon will use a tiny punch tool to remove follicles from the donor area. Although this procedure will still lead to some scarring, it may be less noticeable, and the person will not usually require stitches.
Both techniques are effective, but they can achieve different results in some cases. The authors of a 2019 article state that FUE requires more skill and takes longer than FUSS, but they note that FUE can produce great results if the surgeon has plenty of experience in the technique.
